Former heavyweight champion Mike Tyson has been added to serve as a pallbearer for Muhammad Ali.
Tyson took a red-eye flight from Las Vegas to be in Louisville, Kentucky on Friday, according to Ali family spokesman Bob Gunnell.
Other pallbearers include former heavyweight champions Lennox Lewis and Jerry Ellis, actor Will Smith and members of Ali's family.
Thousands are expected to pay their final respects to Ali during a processional Friday that will wind through the boxing legend's hometown of Louisville, Kentucky.
The 19-mile procession will tour landmarks in Ali's life, including his childhood neighborhood and the gym where he began his boxing training.
